6 Min Walk Test Equation:
| From: | To: |
The 6-minute walk test is a submaximal exercise test that assesses aerobic capacity and endurance. The distance covered over 6 minutes is used as the outcome to determine functional capacity.
The calculator uses the prediction equation:
Where:
Explanation: This equation predicts the expected 6-minute walk distance based on an individual's height, age, and BMI, providing a reference value for comparison with actual performance.
Details: The 6-minute walk test is a simple, inexpensive, and well-tolerated method to evaluate functional exercise capacity. It is widely used in clinical practice and research to assess response to medical interventions, monitor disease progression, and evaluate overall functional status.
Tips: Enter height in centimeters, age in years, and BMI in kg/m². All values must be valid positive numbers.
Q1: What is a normal 6-minute walk distance?
A: Normal values vary by age, gender, height, and weight. Generally, healthy adults walk 400-700 meters in 6 minutes.
Q2: Who should not perform the 6-minute walk test?
A: Individuals with unstable angina, recent myocardial infarction, or other conditions where exercise is contraindicated should avoid this test.
Q3: How should the test be administered?
A: The test should be performed on a flat, straight corridor of known length. Standardized instructions and encouragement should be provided.
Q4: What factors can affect test results?
A: Motivation, learning effect, accompanying medical conditions, and environmental factors can all influence the distance walked.
Q5: How is the predicted distance used clinically?
A: The predicted distance provides a reference value to compare with the actual walked distance. A significantly lower actual distance may indicate impaired functional capacity.
